Is lead iodide soluble or insoluble in water?

Soluble and insoluble saltsSolubleInsolubleMost sulfatesLead sulfate, barium sulfate and calcium sulfateMost chlorides, bromides and iodidesSilver chloride, silver bromide, silver iodide, lead chloride, lead bromide, lead iodideSodium carbonate, potassium carbonate, ammonium carbonateMost other carbonates

All sodium, potassium, and ammonium salts are soluble in water. HgI2 is insoluble in water. PbCl2, PbBr2, and PbI2 are soluble in hot water. The water-insoluble chlorides, bromides, and iodides are also insoluble in dilute acids.

Elementary lead does not dissolve in water under normal conditions (20oC, and pressure = 1 bar). It may however occur dissolved in water as PbCO3 or Pb(CO3)22-. A well-known example of a water soluble lead compound is lead sugar (lead(II)acetate), which derived its name from its sweet nature.

Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2. It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.

Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a colorless crystalline solid at room temperature, highly soluble in water. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic, it is used as a desiccant.

Thus, Fe(OH)3, Al(OH)3, Co(OH)2 are not soluble. 7. Most sulfides of transition metals are highly insoluble. Thus, CdS, FeS, ZnS, Ag2S are all insoluble.

Potassium nitrate is moderately soluble in water, but its solubility increases with temperature (see infobox). The aqueous solution is almost neutral, exhibiting pH 6.2 at 14 °C (57 °F) for a 10% solution of commercial powder.

There is a saying in chemistry that “Like dissolves like” water being a polar solvent dissolves polar and ionic compounds NaNO3 but hydrocarbons are non- polar covalent compounds so they donot dissolve in polar solvent like water rather dissolve in non-polar organic solvents like DMF,DMSO,CS2 etc.

Elemental iodine is slightly soluble in water, with one gram dissolving in 3450 ml at 20 °C and 1280 ml at 50 °C; potassium iodide may be added to increase solubility via formation of triiodide ions, among other polyiodides. Nonpolar solvents such as hexane and carbon tetrachloride provide a higher solubility.

Magnesium is mainly present as Mg2+ (aq) in watery solutions, but also as MgOH+ (aq) and Mg(OH)2 (aq). In seawater it can also be found as MgSO4. Water solubility of magnesium hydroxide is 12 mg/L. Other magnesium compounds are clearly more water soluble, for example magnesium carbonate (600 mg/L).

Barium sulfate is almost insoluble in water. It is not totally insoluble—very small amounts do dissolve. This is true of any “insoluble” ionic compound. If solid barium sulfate is shaken with water, a small amount of barium ions and sulfate ions break away from the surface of the solid and go into solution.

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

The precipitates are the insoluble silver halides – silver chloride, silver bromide or silver iodide. Silver fluoride is soluble, and so you don’t get a precipitate.

Under normal conditions silver is water insoluble. Some other sulphur compounds are more or less water soluble. For example, silver chloride has a water solubility of 0.1 mg/L, maximum. Silver nitrate has a water solubility of 2450 g/L. Silver fluorides are generally water soluble, but other silver halogens are not.

Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl. The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid.

It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.

Iron (II) hydroxide often precipitates in natural waters. Elementary iron dissolves in water under normal conditions. Naturally occurring iron oxide, iron hydroxide, iron carbide and iron penta carbonyl are water insoluble. The water solubility of some iron compounds increases at lower pH values.

The PbO can be changed from massicot to litharge or vice versa by controlled heating and cooling. The tetragonal form is usually red or orange color, while the orthorhombic is usually yellow or orange, but the color is not a very reliable indicator of the structure.
